Application led December 22, 1921. Serial 110.524,06).

To all whom t may concern:

Be it known that I, Form ZoLNEnnvioH, citizen of Russia, residing at9656 Dyer St., Detroit, in the county of `Wayne and State of Michigan,have invented certain new and useful Improvements in Filtering DrinkingCups, of which the following is a specification.

This invention relates to travelers drinking cups, the invention beingintended more particularly for embodiment in travelers drinking cupscomprising a series of telej sco ic sections.

- he invention has for an object to provide a drinking cup of this typehavinglconveniently embodied therewith a iltering medium whereby thewater entering the cup for drinking purposes may be filtered.

For further comprehension of the invention, and of the objects andadvantages thereof, references will be had to the following descriptionand accompanying drawings, and tothe appended claims 1n which thevarious novel features of the invention are more particularly set forth.U

Fig. 1 of the drawings is a perspective view of m improved drinking cup,with the cover t rown back.

Fig. 2 is an axial vertical sectional view of the cup, showingit incollapsed position and with the cover closed.

Fig. 3 is a fra mentary horizontal section, taken on the ine 3-3 of Fig.2. ln constructing my improved cup l provide a base element 10 formedwith an upwardly 'projecting annular flange 10 and telescopicrin 11, theupper ring, indicated specifica ly at 11', having a projecting bead 12at its upper edge. Fitting on this top ring 11 is a stepped ring 14having a downwardly projecting outer lange 15 which engages over thebead 12. This ring 14 presents an upper portion 14 fitting snu ly in thesaid ring 11', and a lower deppen in portion 14 which is, inwardly 0E-set su ciently to engage within the Harige Y on the base element 10 ofthe cup.` The lower ring portion 14.- has an inturned Bange 16 at itsbottom on which the filter member seats. This filter member comprises acharcoal disk 18 having its bottom covered witha double thickness ofcheese cloth or the like as at 19, and its top with a single thickness20. The ilter member may be held in place by frictional engagement withthe ring element 14e.

The cup is rovided with a cover 21 which .is shaped to t in the top ringpart 14', be-

hinged to the` cover adjacent the opposite side thereof` he ring element14 is cui'l out at evenly .spaced intervals as at 24 while theregistering ilange of the cover 21 is formed with complementary pressedout portions 26 which fit in said cut out openings and frictionallyengage the cup ring 11' acting both te hold the cover in place and alsothe filter ring 14. The frictional en agement between these coverportions 26 an the cu ringll' maybe greater than that between t e anges12 .and 15 of the rings 11' and 14.

When it is desired to use the cup the flange 15 is-gripped by thetips ofthe fingers of one hand `and the finger ring 23 is pulled by the otherhand to lift the cover. The cup is then expanded and filled with water,after which the lilter rin carrying with it the filter member, and a sothe cover 21, is lifted from thecup. When use of the cup is iinished thefilter member is replaced, and the 'cover closed.

-Having thus described my invention what I claim as new and desire toprotect by Letlters Patent of the United States is as folows:

1. In combination, a cup, a ring fitting in said cup, a filter membercarried 'by said ring, and a cover hinged to said ring and adapted tofrictionally engage the inner face of the cup., said-ring having cut outortions through which said cover projects into engagement with the cup.

2. In combination a cup, a stepped ring itting snugly in sai cup andhaving a top flange engaging over the to of the cup, a lter membercarried in sai ring, said ring having a number of cut out portionsextending downward from the top thereof, a cover hinged to said top angeand presentin portions `adapted to project through sai cut outportionsinthe ring into frictional enga ement with the cup.

3. n, combination, a cup comprising a series of telescopic sections, astepped ring having an upper-'element tting snugly in the upper one ofsaid sections and an in wardly odset lower element, a filter memberseated in said lower element, a cover adapted to it in said upper ringelement, said uppei,` ring element having a number of cut out perf sietions extending the full height thereof, and said cover havingcorresponding' projections adapted to project radially lnto said cut outportions and frictionally engage the upper cup section.

4. In combinaton, a cup comprising a series of ltelescopic sections, astepped ring having an upper element Iittin snugly in the uper one ofsaid sections an an inwardly o set lower element, a filter member seatedin said lower element, a cover adapted to fit in said upper ringelement, said upper ring@` element having a number of cut out ortionsextending the full height thereof, said cover having correspondingprojections adapted to project radially into said cut out p0rtions andrctionally engage the upper cup section, said ring having a downwardlydepending top ange fitting over the said zo upper cup section.

- sai Leesaee ed to it in said upper ring element, said upper ringelement having a number of cut out portlons extending the full height Jthereof2 said cover having corresponding pro'ections adapted to proJectradiall into cut out portions and frictional y engage the upper cupVsection, said ring having a downwardly depending top flange {itting overthe said upper cup section, said w cover being hinged to said ring.

In testimony whereof I have afiixed my signature.
